Answer: ASA congruency postulate
Step-by-step explanation:
Given: Parallelogram ABCD
To prove: ΔABD ≅ ΔBCD
Construction: Draw auxiliary line BD [see in the attachment]
Proof :- In ΔABD and ΔBCD
∠ADB=∠DBC [if lines are parallel, then its alternate interior angles are equal]
BD=BD [common]
∠ABD=∠BDC [if lines are parallel, then its alternate interior angles are equal]
⇒ΔABD ≅ ΔBCD [ASA congruency postulate]
⇒AD=BC and AB=CD [CPCTC]
- <em>ASA postulate tells if two angles and the included side of one triangle are equal to the corresponding parts of another triangle, then the triangles are congruent.</em>
3/4 of 9.3
3 ÷ 4 = 0.75
0.75 × 9.30 = <span>6.975
therefore the answer is 6.975</span>

No, 23 can't be divided four times.
23/4=5.75
Answer: - 60i - 14j
Step-by-step explanation:
- 18i + 16j - 42i - 30j = - 60i - 14j
